‎In de 14e en de 15e eeuw deed zich in de Bourgondische Nederlanden een uitzonderlijke artistieke bloei voor. De kunstenaars die wij nu Vlaamse Primitieven noemen, ontwikkelden toen een eigen schilderstijl, gekenmerkt door een ver doorgedreven naturalisme en een uiterst gedetailleerde vormweergave, die hen onmiddellijk internationaal befaamd maakte. Dirk De Vos brengt met dit boek een brede introductie tot de schilderkunst van de Vlaamse Primitieven, aan de hand van een twintigtal zorgvuldig gekozen meesterwerken. De hoogwaardige illustraties, waaronder tientallen details, geven de kunstliefhebber de kans om de (in werkelijkheid vaak moeilijk toegankelijke) kunstwerken rustig te bekijken en de schoonheid ervan te ondergaan. ‎

‎First appearance of a milestone paper in genetics being the ""REDISCOVERY"" OF MENDEL'S LAWS OF HEREDITY"" - This paper, together with the two other papers from the same year by Carl Correns and Erich Tschermak, laid the foundations of a new scientific discipline that, in 1906, was given the name ""genetics"", and less than a century later, rose to become the leading science in Western society. This French announcement was published 4 days before his longer paper ""Das Spaltungsgesetzt der Hybride"", in which Mendel is mentioned.De Vries completed most of his hybridization experiments without knowing about Mendel's work. Based on his own results, de Vries drew the same conclusions as Mendel. De Vries published his work in 1900, first in French then in German. In the French report there was no mention of Mendel, but this was amended by de Vries in the German paper. It is possible that de Vries read Mendel's paper before he published his own, and included Mendel's name in the later printing when he realized that other people also knew about Mendel's work. De Vries may have thought that his own conclusions were superior to Mendel's. ""During the 1880s, de Vries became interested in heredity. In 1889 he published Intracellular Pangenesis, in which he critically reviewed previous research on inheritance and advanced the theory that elements in the nucleus, ‘pangenes’, determine hereditary traits. To investigate his theories, he began breeding plants in 1892 and by 1896 had obtained clear evidence for the segregation of characters in the offspring of crosses in 3:1 ratios. He delayed publishing these results, proposing to include them in a larger book, but in 1900 he came across the work of Gregor Mendel, published 34 years earlier, and announced his own findings. This stimulated both Karl Correns and Erich von Tschermak-Seysenegg to publish their essentially similar observations.""

‎Evolution of the Pastoral Novel in Early Modern Spain,‎

‎Turnhout, Brepols, 2009 Hardback, XII+212 p., 175 x 255 mm. ISBN 9782503528946.‎

‎The Evolution of the Pastoral Novel in Early-Modern Spain refreshes and broadens our contemporary view of the intellectual and literary history of Golden Age Spain. It demonstrates that the idealization of love, nature, and country life were not the only motives behind the composition of the pastoral novel. Rather, The Evolution of the Pastoral Novel explores the efforts of the novelists behind these works to establish literary circles, fellowships, and academies, all attempts to revive the literary dialogue of the period. In addition to the novels of Miguel de Cervantes and Lope de Vega, Dominick Finello considers the works of Luis Galvez de Montalvo, Antonio de Lofrasso, Bernardo de Gonzalez de Bobadilla, Gaspar Mercader, Cristobal Suarez de Figueroa, Bernardo de Balbuena, and Gabriel de Corral. These works consistently represent the Spanish pastoral vogues of the late sixteenth and early seventeenth centuries, signalling new combinations of narrative conventions and revealing shifting literary currents hitherto unperceived. This wide range of source material ensures that The Evolution of the Pastoral Novel in Early-Modern Spain is a significant intervention into the history of the novel. New.‎

‎This book presents both an overview of the print production in the 17th century Southern Low Countries and a focused approach to the work of three collaborators of Rubens. Apart from their work as painters, these artists quickly penetrated the world of prints and each dominated a specific market segment. Abraham Van Diepenbeeck was a prolific designer of individual prints and print series. Erasmus Quelinus II often drew models for book-illustrations. Cornelis Schut ran an important workshop which produced many beautiful etchings. The book explores how these artists positioned themselves in an artistic field, operating in a highly competitive field that presented both threats and new opportunities. Their oeuvre is firmly set in a European context, spanning local, regional and international markets. An analysis is made of the relation between prints as reproductions of paintings and prints as autonomous inventions. The book argues that the importance of prints as autonomous creations has been underestimated for the 17th century. The book studies the connections between the three artists and some forty professional engravers who were active in 17th-century Antwerp. Many biographical data on these engravers are presented, and more than 100 prints are published for the first time. Ann Diels (1969) works at the Print Room of the Royal Library of Belgium and teaches the History of European Printmaking at the Free University of Brussels. She has published the New Hollstein volumes on the Collaert Family (2005-2006) and 'The Family Collaert (ca. 1555-1630) en de prentkunst in Antwerpen' (2009). ‎

‎Procopius the Christian Sophist. Catenist, Compiler, Epitomist‎

‎, Brepols, 2024 Hardback, 349 pages, Size:156 x 234 mm, Language(s):English, French, Italian. ISBN 9782503609898.‎

‎Summary The rich literary production of Gaza in the fifth and sixth centuries AD has received quite some attention in recent scholarship. Yet, the figure and work of Procopius the Sophist, as author of catenae, compiler, and epitomist of patristic exegesis, have remained relatively unknown and under-explored. This collection of essays delves deeply into Procopius' exegetical work. At the outset, a strong case is made that one should distinguish between the famous orator of Gaza and "the Christian sophist" Procopius. A first large section of the book deals with the Genesis Epitome that is studied from three different angles: the limited and as a rule critical use of Origen and his tradition; the importance given to Theodore of Mopsuestia's exegesis of Gen 1-3; and the relations between Procopius' Epitome and John Philoponus' De opificio mundi. The section on the Exodus Epitome studies the specificity of Procopius' work in comparison to the Catena on Exodus, the way the material is organised, and the literary genre of the work. The volume further contains contributions on the connections between the Scholia on Kings attributed to Procopius, the type B catena, and the so-called "Catena Lipsiensis"; the relations between Procopius' Catena on Proverbs and other catenae on this book; the sources of the Isaiah Epitome that show a diligent and able compiler at work; and the comparison between the characteristic features of Procopius' Epitomes and those of the Catena III on Obadiah. As a whole, it offers a wide perspective and significantly advances research on, and our knowledge of, Procopius the Christian sophist, a still somewhat mysterious early Byzantine author and scholar.

‎First appearance of these milestone papers in Quantum Physics, constituting the first step in Quantum Field Theory and the invention of the Second Quantifization Method. By these papers Dirac ""gave the foundation for that theory, quantum electrodynamics""(Pais).""A New Radiation Theory. Dirac liked his transformation theory because it was the outcome of a planned line of research and not a fortuitous discovery. He forced his future investigations to fit it. The first results of this strategy were almost miraculous. First came his new radiation theory, in February 1927, which quantized for the first time James Clerk Maxwell’s radiation in interaction with atoms. Previous quantum-mechanical studies of radiation problems, except for Jordan’s unpopular attempt, retained purely classical fields. In late 1925 Jordan had applied Heisenberg’s rules of quantization to continuous free fields and obtained a light-quantum structure with the expected statistics (Bose Einstein) and dual fluctuation properties. Dirac further demonstrated that spontaneous emission and its characteristics—previously taken into account only by special postulates—followed from the interaction between atoms and the quantum field. Essential to this success was the fact that Dirac’s transformation theory eliminated from the interpretation of the quantum formalism every reference to classical emitted radiation, contrary to Heisenberg’s original point of view and also to Schrödinger’s concept of ? as a classical source of field.This work was done during Dirac’s visit to Copenhagen in the winter of 1927. Presumably to please Bohr, who insisted on wave-particle duality and equality, Dirac opposed the ""corpuscular point of view"" to the quantized electromagnetic ""wave point of view."" He started with a set of massless Bose particles described by symmetric ? waves in configuration space. As he discovered by’ playing with the equations, ’ this description was equivalent to a quantized Schrödinger equation in the space of one particle"" this’ second quantization’ was already known to Jordan, who during 1927 extended it into the basic modern quantum field representation of matter. Dirac limited his use of second quantization electromagnetic to radiation: to establish that the corpuscular point of view, once brought into this form, was equivalent to the wave point of view.""(DSB).‎

‎First appearance of these papers constituting Dirac's own theory of quantum mechanics.""Dirac wanted to establish an algebra for quantum variables, or, as he now termed them, q-numbers... He wanted his q-number algebra to be a general and purely mathematical theory that could then be applied to problem of physics. Although it soon turned out that q-number algebra was equivalent to matrix mechanics, in 1926 Dirac's theory was developed as an original alternative to both wave mechanics and matric mechanics. It was very much Dirac's own theory, and he stuck to it without paying much attention to what went on inmatrix mechanics... In the summer of 1926, Dirac published a new and very general version of q-number algebra, this timepresented as a purely mathematical theory. In this paper (offered here) he did not refer to physics at all... The work had little impact on the physics community but seems to have been appreciated by those who cultivated the mathematical aspects of quantum physics. Most of the results obtained by Dirac in his paper ""The Elimination of the Nodes in Quantum Mechanics"" had been found earlier by the German theorists using a method of matric mechanics, but Dirac was able to improve on some of the results and deduce them from his own system of quantum mechanics.""(Helge Kragh).‎
